Consequently, food price policies (subsidies and/or taxes) are proposed to improve the nutritional quality of diets. The aim of the present study was to explore the impact of food price policies on the expenditures and nutritional quality of the food baskets chosen by low-and medium-income households. Methods: Experimental economics was used to examine two price manipulations: i) a fruit and vegetable price subsidy named "fruit and vegetables condition"; ii) a healthy-product subsidy coupled with an unhealthy-product tax named "nutrient profile condition". The nutrient profiling system called SAIN,LIM was used. This system classifies each individual food according to its overall nutritional quality which then allows for a food item to be taxed or subsidized. Women from low-(n = 95) and medium-incomes (n = 33) selected a daily food basket, first, at current prices and then at manipulated prices. The redistributive effects of experimental conditions were assessed by comparing the extent of savings induced by subsidies and of costs generated by the tax on the two income groups. Energy density (kcal/100 g), free sugars (% energy) and the mean adequacy ratio (MAR) were used as nutritional quality indicators. Results: At baseline (before price manipulations), low-income women selected less expensive and less healthy baskets than medium-income ones. After price manipulations expenditures for both income group decreased significantly, whereas, the nutritional quality improved (energy density decreased, the MAR increased). Additionally, the redistributive effects were less favourable for low-income women and their nutritional quality improvements from baseline were significantly lower. Conclusion: Low-income women derived fewer financial and nutritional benefits from implemented food subsidies and taxes than medium-income women. This outcome suggests that food price policies may improve diet quality while increasing socio-economic inequalities in nutrition.

Inherent to such dynamics is the issue of how to design the accompanying environmental policies. Theoretically, spatially targeted environmental policies are considered optimal, since economic agents tune their efforts according to the sensitivity of the milieu where they operate. But, according to empirical analyses, this advantage is undermined by the high cost of implementation, monitoring and enforcement. This paper outlines the conditions required for site-specific policies to be effective at least cost.

Notre point d’entrée est celui de la demande, analysée à partir des comportements observés des touristes. Cette analyse concerne le tourisme d’été dans deux régions : Aquitaine et Rhône-Alpes. Elle est menée à partir des données individuelles recueillies lors de l’enquête "Suivi de la Demande Touristique" des années 2003, 2005 et 2007, données fournies par TNS Sofres à la direction du Tourisme. Ces données nous permettent d’identifier la part relative des différentes pratiques touristiques dans les zones qualifiées de non urbaines. Elles mettent en évidence i) le maintien des séjours qu’on peut qualifier de "retour chez soi" qui n’occasionnent pas de dépense d’hébergement et au cours desquels aucune activité particulière n’est pratiquée ; ii) l’importance des séjours tournés vers la pratique d’activités de plein air et ceux tournés vers la découverte du patrimoine local.

Within this contex a multidisdplinary and pluriannual scientific programme has been set up in 1991. By associating several academic research teams, local authorities as well as farmers, its objectives were oriented towards the development of an agriculture more concerned by groundwater quality, but still profitable. The paper presents a brief summary of the main results which have been obtained after a 4 year period of intensive field work. Three spatial scales are considered: - the field plot ranging from 1 m2 to 1 ha for studying the detailed processes occuring in the soil-plant-atmosphere continuum, the soil being viewed as a bio-physico-chemical reactor, - the farming cultivation system, to test different alternative less polluting scenarios, - the entire plain for evaluating the impact of agricultural practice changes on the groundwater quality time evolution as well as to test the willingness of consumers to financially contribute to set up such alternative programmes.

Tools have therefore been developed to assess this pollution, ranging from simple indicators to complex models. The aim of this paper is to compare indicators and models by analysing results obtained from their individual application to the same area. The pros and cons of each approach are evaluated in terms of both the conditions of their implementation and the results obtained. This comparison helps to guide the choice of a methodology. Rules governing that choice are set in relation to the nature of the diagnosis to perform and the characteristics of the area under study.

This variability depends especially on climate, soil types and farming systems. Our interdisciplinary researches, mainly based on two sites in France, show that space and time heterogeneity influences farm practices to be implemented in order to reduce pollution at the standard level. Hence the most cost-effective farm practices are different from one place to another, depending on local characteristics. Therefore this result emphasises the potential efficiency of spatially targeted policies. Theoretically, such policies are considered optimal, since economic agents tune their efforts according to the sensitivity of the milieu where they operate. But, according to empirical analyses this advantage is counteracted by a high cost of implementation, monitoring and enforcement. In order to maintain the advantage of site-specific policies versus uniform policies, the former have t...

Plus exactement, il s'agit de savoir si la valeur accordée à un produit issu d'une région bénéficiant d'un environnement naturel typé est plus importante que celle accordée à un produit issu d'une région dont l'environnement est moins attractif. Pour répondre à cette question, nous recourrons à une analyse en laboratoire qui compare deux fromages issus de deux territoires des Alpes françaises. Les résultats montrent notamment que les aménités d'un territoire, même si elles participent de la valeur affective d'un produit, ne peuvent être valorisées économiquement que s'il y a congruence entre le territoire et le produit.

This is achieved through comparing two pollution control programs with respect to their costs, water quality impacts and correlation between abatement cost and polluting emissions. The fieldwork was done in a watershed, near French Alps. It was carried out by economists in close relation with agronomists and hydrologists. The difficulty of the assessment of the environmental impact of the foreseen technological scenarios is overcome by developing an indicator of environmental effectiveness able to grasp the level of nitrate pollution of agricultural origin and to check whether the pollution control programs are able to reach the given environmental target or not. The results

Our method consists in using a bio-physical model to evaluate the environmental and economic impacts of various scenarios characterized by a set of farm practices. The cost-effectiveness of each scenario is calculated for a catchment area located in the northeast of France, for various climatic years and under different assumptions of crop prices. The results show that it is not realistic to obtain a rapid reduction of nitrate concentrations by implementing the scenarios tested. In the long run and irrespective of the economic context simulated, the optimum scenario in the case studied is one that combines integrated fertilization with the introduction of catch crops. Our findings thus highlight the effectiveness of catch crops that are able to reduce variability of nitrate concentration and thus significantly reduce the risk of exceeding environmental constraints. They therefore provide some recommendations for policy-makers. D
